Imagine my surprise when I read the news that Apple is being sued over its scrolly Mighty Mouse.

At last, I though, a victory for consumer rights.

But it turns out the lawsuit is to do with some animated rodent superhero, and nothing at all about a computer mouse that very quickly gums up with dust, rendering it next to useless within a few months.

You're not supposed to have to spit at your computer equipment, you know. But with the Mighty Mouse it sure does help.
